ExtractStream + new SVR2000 FIXED!

[jeremyjgordonhome]

Hi,

In the "from scratch" code that I wrote, I do do this in my debug 
routines. I set up my program to scan the sectors (over a period of 
a few hours) of each partition and print anything that didn't have a 
MAGIC or has a non-zero FSID, or has an FSID:Sector mapping that 
didn't fit the original ExtractStream formula.

This is how I noticed that /dev/hda11 and /dev/hda13 don't seem to 
have any MFS database entries, but I saw all the "missing" FSID's 
on /dev/hda12 that were failing to be accessed by ExtractStream 
on /dev/hda10.

The next question I have (and I haven't had time to program in a two 
days) is now that I have identified the sector map entry for offset 
and size of actual tyStream data, how do I interpret that 
for /dev/hda13. Is the sector map offset found in the MFS 
on /dev/hda12 offset from zero on /dev/hda13 or is it offset from the 
beginning of the sum of the sizes of /dev/hda12 + /dev/hda13 or what?

I'm sure the answer isn't that hard, but I just haven't had time to 
mess with it yet.

Regards,

Jeremy
